Objective To describe status of cancer-related fatigue (CRF) and its trajectory during three different time node for the operation, chemotherapy, and radiotherapy among breast cancer patients. Methods The convenience sampling method was used for 242 cases diagnosed with breast cancer which prepared for breast cancer resection, prepared to be treated with adjuvant chemotherapy and radiotherapy, and conformed to the sample standard from a tumor hospital and two affiliated hospital of medical college from February 2014 to November 2015 in a city. The follow-up survey of CRF was conducted respectively in the three different point-in-time for one week after the operation, at the end of chemotherapy and radiotherapy. Results After the operation mean rating for general fatigue was mild (2.59±2.41) points, and approximately 76.0% (184/242) patients experienced fatigue to low- grade degree; After the chemotherapy fatigue was significantly increased (6.57 ± 2.43) points, and 75.2% (182/242) patients accounted for severe fatigue; After the radiotherapy mean rating for fatigue was moderate (4.38 ± 2.46) points, and 57.0%(138/242) patients suffered to moderate fatigue. During the whole treatment period the level for general fatigue and four dimensions of fatigue were in the unstable state ofwaveof fluctuations with mild, severe, moderate, and fatigue were statistically different in three different stages of treatment ( F= 43.16,P=0.000). The age and operation method were associated with CRF in thephaseofoperation(age t=7.365, P=0.003; operation method t=5.166, P=0.009), chemotherapy (age t=9.835, P=0.000; operation method t=3.313, P=0.025) and radiotherapy (age t=9.014, P=0.000;operation method t=10.392, P=0.000). Conclusions There is a certain difference with CRF of breast cancer patients at different stage of rehabilitation treatment. There are two factors that could affect CRF such as age and operation method in the whole rehabilitation treatmentperiod.

Objective:To explore the relationship among the cancer-related fatigue,coping styles and quality of life in breast cancer patients with chemotherapy.Methods:A total 120 female breast cancer patients were selected as the subjects.The instrument used for data collection was a questionnaire that was composed of four parts:the demographic data form,the Revised Piper Fatigue Scale (PFS),Jalowiec Coping Scale (JCS),Quality of Life Questionnaire-Core 30 (QLQ-C30),and Quality of Life Questionnaire-Breast 23 (QLQ-BR23).The statistical software SPSS was used for data analysis.Cancer-related fatigue,coping styles,quality of life and their related factors were determined by nonparametric tests.Spearman correlation coefficient was used to investigate the relationship among cancer-related fatigue,coping styles and quality of life in breast cancer patients with chemotherapy.Results:There was a significant negative moderate correlation between cancer-related fatigue and the quality of life (r＝-0.24,P<0.01),and negative correlation between cancer-related fatigue and the total health status (r＝-0.39,P<0.01).The positive coping styles including optimistic and confronting were negatively correlated with cancer-related fatigue (r＝-0.25,-0.18，Ps<0.05),and were positively related to the functional domain of quality of life(r＝0.35，0.21， Ps<0.05).The positive coping styles including emotive,fatalistic,and palliative were positively correlated with cancer-related fatigue (r＝0.25,0.18,and 0.28， Ps<0.05),and were negatively correlated with the functional domain of quality of life (r＝-0.40,-0.32，Ps<0.05),and emotive and fatalistic were positively related to the symptomatic domain of quality of life(r＝0.40,0.28,Ps<0.05).Conclusion:There exists a certain degree of correlation among cancer-related fatigue,coping styles and quality of life in breast cancer patients with chemotherapy,which may guide the clinical care.

OBJECTIVE: To investigate the characteristics and regularity of adverse drug reactions (ADR) occurred in our hospital. METHODS: 286 ADR cases collected from our hospital from Jan. 2007 to Jun. 2009 were analyzed statistically. RESULTS: There were 3 severe ADR cases. 213 ADR cases were caused by anti-infection agents in our hospital (74.48%), followed by 38 ADR cases caused by TCM preparations (13.29%). Main clinical manifestation of ADR cases were lesion of skin and its appendants in 146 cases (44.92%), followed by 62 cases of lesion of digestive system (19.08%). 202 ADR cases were caused by intravenous administration (70.63%). CONCLUSION: Pharmaceutical monitoring and administration system should be established and improved. Great importance should be attached to ADR monitoring to reduced the incidence of ADR in our hospital.

OBJECTIVE:To explore the clinical role of two-hour(C2)of CsA in allogeneic hematopoietic stem cell transplantation.METHODS:The whole blood CsA concentration of 9 patients of C0 and 12 of C2 were determined by FPIA method . RESULTS: The satisfactory immunosuppressive concentration was found as follow: C0 was 200～400 ?g?L-1and C2 was 500～700 ?g?L-1.Both C0 and C2 could predict the acute rejection and side-effects,but C2 is more effective.CONCLUSION:The factors that affect the whole blood concentration of CsA were complex. CsA blood concentration monitoring can be used to guide rational use of CsA,but C2 is more effective than C0.

AIM: To explore the effects of peroxisome proliferator-activated receptor γ (PPARγ) on the activity and expression of γ-glutamylcysteine synthetase (γ-GCS), and its role in rats with chronic obstructive pulmonary disease. METHODS: COPD model was established by the method of combining fumigation and lipopolysaccharide (LPS) intra-tracheal dripping. Meanwhile, some of the COPD rats were administered with rosiglitazone (RGZ), a PPARγ activator. The pulmonary function and the pathological changes were determined. ROS content and γ-GCS activity in lung tissues were detected. The levels of PPARγ, γ-GCS mRNA and protein expression in lung tissues were measured by immunohistochemistry, Western blotting, in situ hybridization (ISH) and reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The pulmonary function (FEV_(0.3), FEV_(0.3)/FVC%, PEF) were significantly improved in RGZ group compared to COPD group. Under light microscope, lung pathological changes in COPD group conformed to pathological features of COPD. The pathological changes of lung tissue were obviously reduced in RGZ group compared to COPD group. In RGZ group, ROS content was obviously reduced and γ-GCS activity significantly increased compared to COPD group. Protein and mRNA expressions of PPARγ and γ-GCS in COPD group significantly higher than those in control group (all P<0.01), and those in RGZ group was markedly increased compared to COPD group (all P<0.05). Linear correlation analysis showed that PPARγ protein was positively correlated with γ-GCS activity (r=0.634, P<0.01), and was no significantly correlated with ROS content (r=0.214, P>0.05). PPARγ protein was positively correlated with γ-GCS protein and mRNA (r=0.553, r=0.442, all P<0.01). CONCLUSION: PPARγ activation by RGZ reduces the extent of COPD oxidant/antioxidant imbalance, which plays an important role in the prevention and treatment of COPD. In addition, PPARγ may play an important antioxidant protection role by reducing ROS production, and increasing activity and gene expression of γ-GCS in the lung.
